Consider the following reaction: 2A + 3B   2C

If you have 2 moles of A and 6 moles of B, what is the maximum number of moles of C that can be made by the reaction?

a. 2 moles C

b. 4 moles C

c. 6 moles C

d. 8 moles C

Interpretation Introduction

Interpretation:

The maximum number of moles of C produced in the given reaction is to be predicted.

Concept Introduction:

The coefficients in a chemical reaction give information about the number of molecules or atoms involved in the reaction.

The coefficients basically represent the number of moles of the substances involved in the reaction.

Also, the coefficients of a balanced reaction give information about the ratio in which the substances react and produced in the reaction.

Explanation of Solution

Reason for correct option:

From the given chemical equation, 2A + 3B2C, it can be concluded that 2 moles of A react with 3 moles of B to produce 2 moles of C. Even though there is enough of B is present to produce more moles of C but the 2 moles of A limit the amount of product that can be produced. Therefore, a maximum of 2 moles of C can be produced.

Hence, option (a) is the correct answer
